It's also known as an engine retarder brake. It opens the exhaust valves in the cylinders after the compression cycle. This releases the trapped air, and slows the vehicle down.
Jake brake actually refers to the compression brakes made by Jacobs Vehicle Systems - however, it's become a generic term applied to all such systems.
Not all retarders are engine compression brakes - there are also exhaust brakes, which can be in place of, or in conjunction with, engine compression brakes. These close off the flow of exhaust, and tend to sound more like vacuum cleaners.
You ONLY use the clutch brake when you're at a complete stop.
to truck drivers to hit the Jake brake is to pull on a handle on t he sterring column and shut down the engine
No such thing. Dodge hasn't manufactured semi trucks since the 1970s, IIRC. When they were purchased by Daimler A.G., Daimler already owned Freightliner, and saw no need to reintroduce a Dodge semi truck.
It cause down shifting is making the engine roar most trucks hardly use a jake brake

Who invented the Semi-truck?
Usually busses do not have retarders because they are too loud and cannot be used inside most city limits on a semi truck they have a switch to turn on the jake brake (engine brake, or retarder) when the switch is on and you let the accelerator all the way up the brake takes over. All a retarder does is use your air brakes (or hydraulic) less to prevent overheating that will lead to brake loss.
If the semi truck knocked on the garbage truck, yes.
The governor, purge valve, and regulatory valves to the brake chambers regulate the air pressure.
A vehicle with 18 wheels is commonly known as a "semi-truck" or "tractor-trailer."
Try the tractor with a different trailer, the pig tail is most likely not connecting properly.
